a) \(\frac{1}{8} + \frac{3}{16} = \frac{2}{16} + \frac{3}{16} = \frac{5}{16}\)
б) \(4,8 - 5,9 = -1,1 = -\frac{11}{10}\)
в) \(- \frac{4}{9} \cdot 1\frac{7}{11} = - \frac{4}{9} \cdot \frac{18}{11} = - \frac{4 \cdot 18}{9 \cdot 11} = - \frac{4 \cdot 2}{1 \cdot 11} = - \frac{8}{11}\)
г) \(-4,8 : (-1,4) = \frac{48}{14} = \frac{24}{7} = 3\frac{3}{7}\)
д) \(-1,25 : (-0,25) = \frac{1,25}{0,25} = 5\)
e) \(-1,6 : (-1,2) = \frac{16}{12} = \frac{4}{3} = 1\frac{1}{3}\)
